ITEM NAME:100A/100mA Opening Closing Current Transformer Three-Phase Opening Type Module Descriptio n Description: Features: This is a mini split base current transformer; it's the smallest one compared to the similar products (output 100MA). The diameter of inner hole is 16mm, the accuracy is ≠¤0.5 grade. Using snap joint structure, it can be fixed to the cable directly through nylon ties. Built-in input coil; small and light, easy to install. Fully enclosed, good mechanical properties and environmental resistance, strong voltage isolation capability, safety and reliability. Application: 1. The current transformer is used for energy meter in special; AC 220V, 380V power supply can both be applied. 2. When you fix the energy meter, you don't need to cut off the power if you use this product. Note: 1. The CT primary should be connected in series with the test current loop, the secondary should be as work in the short-circuit state. 2. The secondary circuit is not allowed open circuit, so please do not install fuse.
